"Finger pads" in Spanish?
Ahora sabemos.

M. H. Graham just sent me a complimentary copy of her Ahora Hablo! Medical Edition, a handy paperback of Spanish terms useful for medical professionals.

It seems useful and relatively error-free (there's the odd typo, but no big deal). Had I seen it in a store, I would have bought it - it's only ten dollars. The most important feature of the book is that the words and phrases it includes are used nearly every day by many healthcare workers -- fun conversation starters like What color is your stool? and Do you have asthma? My Spanish is fluent (though not native) and I can testify that I've already learned a number of words from this book I didn't know before.
